Description
Diphenhydramine (DPH) is a first generation antihistamine which is a potent antagonist of the human H1 receptor (Ki = 11.7 nM). Like many first generation antihistamines, DPH readily crosses the blood-brain barrier and produces diverse cognitive and psychomotor effects. DPH also antagonizes muscarinic cholinergic receptors (Ki = 100 to 260 nM for M1 through M5), increasing the range of central nervous system effects and applications.Related product price
